To be fair, his argument seems to be more about maintaining a pace of development as an openly unfinished early access game who already has paying customers.

I’m still on the side of the other guy, who can’t control that fact that a game that he listed as unfinished as a solo dev/small team blew up too early. I think that for a small team trying to build something that’s not tiny, having continuous feedback from a dedicated group of customers allows you to make a better game, and having income allows you to spend more time developing it.

I would generally not recommend buying an early access game unless you either think it’s already at a level you’re happy with or you really value that back and forth process and want to “invest” in helping the game you value get made. You need to do it with your eyes open. But I don’t think it’s an inherent failing to not magically build a studio when a game blows up.
